Abstract
Detection of ship wakes is utterly important for ship traffic monitoring, security of sea borders, etc. Among standard detection methods there are radar and acoustic sensing, photographing, hyperspectral measurements, and water sample analysis. However, these methods are hardly suitable for detecting wakes of light high-speed boats. An alternative is optical methods, in particular laser remote sensing. In this work, laboratory experiments on laser remote sensing of water perturbed by a propeller rotating at up to 20 000 rpm are described. A long (over 5 h) decrease in the integral of the band of OH stretching vibrations inH2Omolecules in the Raman scattering spectrum and a blueshift of theOHband center by 2.5 to 3 cm−1 are demonstrated.
